Description

Pi-hole is a DNS sinkhole that protects devices from unwanted content without installing any client-side software. From 6.0 to 6.4.2, a user with code execution as the unprivileged pihole user can escalate to root by replacing /etc/pihole/logrotate. The replacement is laundered to root:root ownership by pihole-FTL-prestart.sh and then parsed as root by the daily pihole flush cron, executing firstaction shell as uid 0. This issue is fixed in version 6.4.3.

CVE-2026-54684
jadx is a Dex to Java decompiler. From 1.5.2 to 1.5.5, a malicious .xapk file can cause jadx to write attacker-controlled archive entry contents outside the intended XAPK plugin temporary unpack directory because XApkLoader resolves each entry name directly with tmpDir.resolve(fileName) after a CWD-based ZIP security check. When jadx is launched from a directory that is an ancestor of the config directory, the arbitrary write can plant a JAR in plugins/dropins, and the next jadx run loads the JAR with URLClassLoader and ServiceLoader, executing attacker-controlled plugin code. This issue is fixed in version 1.5.6.

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as .rclonelink text objects and recreates them on a local destination without validating the target, allowing an attacker-controlled remote to plant an escaping symlink and cause a following object write to land outside the destination with attacker-chosen contents. This issue is fixed in version 1.74.4.
